| Component | Maintenance | Notes and precautions |
| Shaft support bushings | Periodical checks (at least once a month) | The Neoprene bushing of the shaft support, during navigation in waters with sandy suspensions, may wear rapidly. The bushing wear causes a vibrations increase. With the yacht in a dry shore, a good technician can easily evaluate, by moving the shaft, if the wear is so bad as to need the bushing to be replaced. |
| Assembly/disassembly | ||
| Stuffing box seal | Maintenance and check | With yacht moored at the marina, daily and before set up navigation. |
| Shaft lines | Periodical checks (at least once a month) | It is essential to keep always the propellers and shafts clean; the formation of parasites or the presence of foreign bodies like cables, cloths or plastic bags lead to propulsion power reduction, to propellers cavitation with consequent surface damage, and to vibrations causing damages to the stuffing box seals and to the bushings of the shaft supports. Checking and eventual cleaning may be carried out with the yacht in a dry shore or with the help of a diver. To clean scrape the barnacles, without engraving the metal, polish them with sand paper at thin grain. |
